Renormalization group analysis for the quasi-1D superconductor BaFe${}_2$S${}_3$

Elio J. König, Alexei M. Tsvelik, Piers Coleman

Motivated by the discovery of superconductivity in the two-leg, quasi-one dimensional ladder compound, BaFe${}_2$S${}_3$ we present a renormalization group study of electrons moving on…
